pseries now allows PCIe devices (both emulated and VFIO), although its PCI bus is in most respects a plain PCI bus - this uses paravirtualized access methods to PCIe extended config space defined in the PAPR spec.
However, because the bus is not PCIe, it means that virtio-pci and XHCI devices will present themselves as plain PCI rather than PCIe, which would be preferable. This patch uses the new hook to override the behaviour for such PCI/PCIe "hybrid" devices to allow PCIe virtio-pci and XHCI on pseries.
